Title: Unit 8: Part 2 - Mechanical handling


1
Unit 8 Part 2 - Mechanical handling
  • NEBOSH Health Safety Certificate

2
What you need to know
  • The hazards, precautions and procedures necessary
    to ensure safety in the use and maintenance of
  • Fork-lift trucks
  • Manually operated load moving equipment (sack
    trolleys, pallet trucks, etc)
  • Lifts, hoists, conveyors
  • and cranes.
  • Lifting Operations Lifting Equipment
    Regulations (LOLER) 1998 requirements and
    statutory examination of lifting equipment

3
Mechanical handling and lifting equipment
  • Conveyor hazards
  • In-running nip between drive-rollers and belt
    quarry accidents during cleaning at bottom
    roller
  • Entanglement
  • With transmission machinery chain sprocket
    drives
  • Conveyor belt/slats.
  • Elevator hazards
  • Because loads lifted to height eg. Materials
    hoist on construction site the loads can fall
    onto people below if a unsecured or b people
    are allowed under elevator while it is working.

Slat and roller conveyors

Fork-lift trucks
  • Accidents
  • Overturning, due to high speed turns, ramp turns,
    driving with raised load, uneven road surface
    most fatals
  • see Reg 26 27, PUWER 98 and vehicle restraints,
    ROPS.
  • Overloading, unstable loads
  • Collisions with
  • Overhead obstructions
  • Racking systems eg. Wrexham warehouse
  • Pedestrians, other vehicles.
  • Main causes
  • Lack of driver training - see HSEs Rider
    operated lift trucks - operator training COP 26
    and PUWER Regs 89
  • Lack of maintenance for safety purposes - PUWER
    98,
  • Reg 5

Fork-lift trucks 2
  • Other hazards
  • Fire and explosion
  • Battery re-charging, or
  • Flammable atmosphere eg. Paint factory
  • Exhaust gas/fumes in confined spaces
  • Hydraulic failure on lifting forks
  • Unauthorised use as a working platform see
    example.

11
Lifts, hoists
  • Definition
  • ..incorporates a platform or cage and is
    restricted in its movement by guides. Handbo
    ok
  • Lifting Operations and Lifting Equipment
    Regulations 1998
  • features
  • sound mechanical construction - strength
    stability Reg 4
  • interlocked doors or gates - Reg 5
  • passenger lifts also need
  • automatic braking system to prevent overruns
  • min. 2 suspension ropes each can carry max.
    working load
  • safety device to support lift if ropes fail.
